Abstract

A large number of studies have shown that miRNAs are important regulators of epithelial-to-mesenchymal transition (EMT) and are associated with metastasis in epithelial ovarian cancer (EOC). MiR-361-5p has been shown to play pivotal roles in tumorigenesis and metastasis; however, a role for miR-361-5p in EOC has not been reported. In this study, we found that miR-361-5p was significantly down-regulated in EOC tissues and cell lines. In addition, over-expression of miR-361-5p inhibited the migration and invasion of EOC cells in vitro. MiR-361-5p influenced the expression of the EMT-associated proteins by upregulating the epithelial marker E-cadherin and downregulating the mesenchymal markers, N-cadherin and vimentin. Further studies identify miR-361-5p directly targeted Ribosomal L22-like1 (RPL22L1) and c-Met. Moreover, miR-361-5p repressed the Akt/mTOR pathway after c-Met inhibition. Reintroduction of RPL22L1 and c-Met reversed miR-361-5p-induced EMT suppression. Consistently, inverse correlations were also observed between the expression of miR-361-5p and RPL22L1 or c-Met in human EOC tissue samples. Taken together, miR-361-5p inhibited the EMT progression in EOC cells by targeting RPL22L1 and c-Met/Akt/mTOR signaling.

摘要

大量研究表明,微小RNA(miRNAs)是上皮-间质转化(EMT)的重要调节因子,与上皮性卵巢癌(EOC)的转移相关。已证明miR-361-5p在肿瘤发生和转移中起关键作用;然而,miR-361-5p在EOC中的作用尚未见报道。在本研究中,我们发现miR-361-5p在EOC组织和细胞系中显著下调。此外,miR-361-5p的过表达在体外抑制了EOC细胞的迁移和侵袭。miR-361-5p通过上调上皮标志物E-钙黏蛋白并下调间质标志物N-钙黏蛋白和波形蛋白来影响EMT相关蛋白的表达。进一步研究确定miR-361-5p直接靶向核糖体L22样1(RPL22L1)和c-Met。此外,c-Met抑制后,miR-361-5p抑制了Akt/mTOR通路。重新引入RPL22L1和c-Met可逆转miR-361-5p诱导的EMT抑制。同样,在人EOC组织样本中也观察到miR-361-5p与RPL22L1或c-Met表达之间呈负相关。综上所述,miR-361-5p通过靶向RPL22L1和c-Met/Akt/mTOR信号传导抑制EOC细胞中的EMT进程。
